问题描述
由于对此问题的答案，我已经开发了plotly plot，其中buttons链接到其legend，在其中单击legend会更改每个包含T/F状态的reactive variable的状态，从而重新呈现链接到每个actionbuttons的actionbuttons trace(数据组).另一个javascript在相反的方向上执行相同的操作，单击button隐藏/显示plot中的trace + legend项.
Thanks to answers on this previous question, I have developed a plotly plot with buttons linked to its legend, where clicking the legend changes the state of a reactive variable containing T/F state for each of them, and thus re-renders the actionbuttons linked to each trace (data group). The other javascript does the same in opposite direction, clicking a button hides/shows that trace + legend item in the plot.
现在我希望通过一个新按钮+ selectinput添加另一个交互
简短的问题:
如何使单击一般按钮(#0)，
在TRUE/'legendonly'
之间更改图例状态开关对于情节j(#1)的迹线n，
其中n = input$SelectTrace(#2)
通过在该actionButton
The question in short:
How to make clicking a GENERIC button (#0),
change the legend status switch between TRUE/'legendonly'
for trace n of plotly plot j (#1),
where n = input$SelectTrace (#2)
by using javascript + onclick argument on that actionButton
0 actionButton在这里称为'SwitchExt'
1因为我有多个
，所以它需要定位到特定的plotly plot2 a selectInput将走线作为选择
0 actionButton called 'SwitchExt' here
1 It needs to target a specific plotly plot since I have multiple
2 a selectInput with the traces as choices
详细说明:
现在我有以下小问题:在我的应用程序的另一个条件面板中，向用户显示了一组具有相同数据的不同图块: -用户可以选择要突出显示的迹线，其旁边的按钮将根据T/F状态列表显示第一个绘图中的该迹线是否打开/关闭，然后该按钮将显示蓝色/红色，并且链接到选定的跟踪.
Now I have the following little problem: In my app, in another conditional panel, the user is shown a different set of plots with the same data: - the user can choose which trace to highlight, a button next to it will show whether this trace in the first plot is on/off based on the list of T/F statusses, and then this button will show blue/red, and is linked to the trace selected.
场景:用户选择了第n组，点击新的actionButton 'SwitchExt'这会触发flipYNb_FP1(n)，actionButton YNbuttons... YNb <- YNElement(n) ....
Scenario: The user selected group n, clicks the new actionButton 'SwitchExt'this triggers flipYNb_FP1(n), actionButton YNbuttons... YNb <- YNElement(n) ....
if(values$dYNbs_cyl_el[[YNb]] == TRUE) {
将导致按钮n更改状态.
will cause button n to change state.
我可以使它也更改values$legenditems[n]，但是在我的绘图代码中，values$legenditems包裹在isolate({ })中，以防止链接到legend的javascript更改绘图时重新渲染.
I can make it also change values$legenditems[n], but in my plot code, values$legenditems is wrapped in isolate({ }) to stop the plot from re-rendering whenever the javascript linked to the legend changes it.
解决方案的概念:基本上，我认为我需要的不是直接更改values$legenditems列表，而是要有另一个javascript，它通过'onclick'链接到actionButton 'switchExt'，并以input$SelectTrace作为输入，并且然后将legendstatus更改为类似于javascript js1的方式，但是随后使用document.getElementById获取input$SelectTrace的值，将其转换为numeric，并更新legendstatus.
Concept of the solution: Basically what I think I need, is rather than changing the values$legenditems list directly, is to have another piece of javascript that is linked to actionButton 'switchExt' by 'onclick' and takes input$SelectTrace as input, and then changes the legendstatus similar to how javascript js1 does it, but then using document.getElementById to grab the value of input$SelectTrace, turn it into numeric, and update the legendstatus.

解决方案:经过一些意想不到的行为的挣扎之后，我发现我需要删除switchExt-plot1的观察者，以防止按钮两次翻转.
solution:After some struggle with some unintended behavior I figured out that I needed to remove the observer for switchExt-plot1 to stop buttons from flipping twice.
observeEvent(input[['SwitchExt-plot1']], {
flipYNb_FP1(as.numeric(input$SelectTrace))
})

推荐答案
我不确定我是否理解，但让我们从一些内容入手.
I'm not sure I understand, but let's start with something.
js1 <- c(
"function toggleLegend(id){",
" var ids = id.split('-');",
" var plotid = ids[1];",
" var index = parseInt(ids[2])-1;",
" var plot = document.getElementById(plotid);",
" var data = plot.data;",
" var v0 = data[index].visible || true;",
" var v = v0 == true ? 'legendonly' : true;",
" Plotly.restyle(plot, {visible: v}, [index]);",
"}",
"function toggleLegend2(){",
" var index = parseInt($('#SelectTrace').val())-1;",
" var plot = document.getElementById('plot1');",
" var data = plot.data;",
" var v0 = data[index].visible || true;",
" var v = v0 == true ? 'legendonly' : true;",
" Plotly.restyle(plot, {visible: v}, [index]);",

actionButton(inputId = 'SwitchExt', ......, onclick = "toggleLegend2()")
